A glide bearing for guiding axial movement between inner and outer telescoping columns may include first and second spaced apart contact surfaces, and a resilient wall extending therebetween and having an outer convex surface defining an apex. A span between the apex and a plane defined between the first and second contact surfaces is greater than a width of a space between the outer surface of the inner column and the inner surface of the outer column. The glide bearing is configured to be disposed within the space with the first and second contact surfaces contacting the outer surface of the inner column, with the apex contacting the inner surface of the outer column and with the resilient wall deflecting inwardly toward the plane to accommodate the space in response to a force of the inner surface of the outer column acting against the apex.

A telescopic table frame part, in particular a height-adjustable table leg (26), comprising an outer tube (12) and an inner tube (10) which can be moved relative to the former and which is guided by means of a sliding guide, characterized in that the sliding guide comprises at least one injection-molded sliding element (24) made from a slide-promoting plastic, a method for producing a sliding guide for guiding an inner tube (10) in an outer tube (12) movable relative thereto of a telescopic table frame part, comprising attaching of at least one sliding element (24) made from a slide-promoting plastic onto the inner surface (23) of the outer tube (12) or onto the outer surface (25) of the inner tube (10) by injection molding, wherein said plastic is introduced into the inside of the inner tube through an injection molding tool access opening (16) in same, and an apparatus for carrying out the method.

The invention concerns a telescopic rail comprising a first rail element with two running surfaces, a second rail element with two running surfaces, at least one rolling body cage for positioning a plurality of rolling bodies. Such telescopic rails are found to suffer from the disadvantage that the rail elements and the rolling body cages all have to be designed to be moveable relative to each other. Accordingly the invention proposes providing a telescopic rail in which the rolling body cage is secured to the first rail element so that the rolling bodies perform a sliding movement with respect to the running surfaces of the first rail element and the rolling bodies perform a sliding movement with respect to the running surfaces of the second rail element or roll on the running surfaces of the second rail element.

A sofa bed sliding system for a sofa bed is provided. The sliding system is forming a connection between a moveable sofa bed part and an associated frame structure, wherein said sliding system includes at least one sliding surface being coated with a lacquer including a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

A dual-column office table includes two oppositely disposed stationary upright columns with a connecting rod transversely connected therebetween, two guiding columns separately disposed in the two stationary upright columns, at least one steel ball sleeve fitted on either guiding column, two driving units separately disposed in the two guiding columns, and a table top to which a top portion of each guiding column is fixedly connected. A bottom end of each guiding column is provided with a limiting structure protruding outward. A bottom end of the each driving unit is fixed to a respective table base provided at bottom portion of each stationary upright column. The table top has a bottom surface fixedly connected with a fixing seat and is provided with a lifting control switch, the lifting control switch being connected with the driving units and having an end disposed in the fixing seat.

A glide bearing for guiding axial movement between inner and outer telescoping columns may include first and second spaced apart contact surfaces, and a resilient wall extending therebetween and having an outer convex surface defining an apex. A span between the apex and a plane defined between the first and second contact surfaces is greater than a width of a space between the outer surface of the inner column and the inner surface of the outer column. The glide bearing is configured to be disposed within the space with the first and second contact surfaces contacting the outer surface of the inner column, with the apex contacting the inner surface of the outer column and with the resilient wall deflecting inwardly toward the plane to accommodate the space in response to a force of the inner surface of the outer column acting against the apex.

A table leg includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube and having two pairs of parallel walls, and a plurality of rotating members rotatably mounted to one pair of the parallel walls of the movable inner tube and partially protruding out from an outer surface of the movable inner tube and stopped against an inner surface of the fixed outer tube, such that the rotating members are rotatable when the movable inner tube is moved relative to the fixed outer tube.

A bed frame includes a backrest, a bedstead and a plurality of connectors to couple the backrest with the bedstead. A connector includes first, second, third and fourth segments, in which each of the second, third, and fourth segments extends from a lower side of the first segment. A first slot is formed between the second and third segments to accommodate a bar of the backrest, and a second slot is formed between the third and fourth segments to accommodate a bar of the bedstead. When the bed frame is assembled, each connector in the plurality of connectors is fixedly coupled with the bar of the backrest, and snap-fitted on the bar of the bedstead.

A device for rocking a hammock holding a human is described. The device includes a frame, a lever arm, a solenoid, a cord, and a signaling device. The lever arm pivots about a pivot point to move within the frame. The solenoid is connected to the lever arm to apply a force to rotate the lever arm. The lever arm is connected via the cord to the hammock. As the lever arm moves from one position to another within the frame, the signaling device detects the position of the lever arm and signals to turn on the solenoid to apply a force to the lever arm to rock the hammock.

A table leg includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube and having two pairs of parallel walls, and a plurality of rotating members rotatably mounted to one pair of the parallel walls of the movable inner tube and partially protruding out from an outer surface of the movable inner tube and stopped against an inner surface of the fixed outer tube, such that the rotating members are rotatable when the movable inner tube is moved relative to the fixed outer tube.
